    In the process of planning a new shed installation, currently thinking about running power, alarm and ethernet cables. The alarm cable will be used for a PIR.

    I have an existing bog standard alarm system in the house, was put in during the build by the original owners, by the electrician i'd say. Can't see a make or model on it anywhere..

    I'm looking at about a 25 meter run, and am planning an underground run. I'll run the cables and then get an electrician and alarm guy in to do the terminations. Ethernet, I'll handle myself.

    My questions:
    Can i put all the cables in the one conduit?? Will I need shielded cable for interference??
    Does the alarm cable need to be special type of cable for underground??
    Any other issues I'm not thinking of??

    Did you use shielded cat5, and how deep did you bury the ducting?

    Its just duct grade cat5e...each twisted pair is shielded and then an outer shield..like poly poly cable..armour cat5e is overkill if you put it in a duct..duct is wavin 4inch buried about a metre but thats just cause we had a digger.id imagine you could bury it a foot or two in a back garden...mine was across a driveway

    We use hydrodare to run cables in. Very tough and flexible as well.
